The first thing you notice on a Darjeeling estate is that you can't walk it. The slope is too steep. The pickers wear plastic boots and balance like they were born on the mountain, which they were. The leaves are brought down by hand — there are no machines that work at this gradient — and the path between picking and processing is measured in flights, not steps.
Yunnan is different. The terraces are wider, gentler, but the sourcing geography is fragmented. The all-bud tea we sell as Yunnan Golden Tips comes from a co-op of forty families who pool their picks because none of them produces enough alone to justify a dryer. The co-op's processing facility is a single room with three orthodox dryers, two cup-tasting tables, and a whiteboard with the day's temperatures in chalk.
Uji is a tradition more than a geography. The matcha fields are shaded by tarpaulin canopies for the three weeks before harvest, which forces the plants to overproduce chlorophyll — that's where the electric green comes from. The leaves are de-stemmed, de-veined, dried, and stone-ground in a ritual that hasn't changed in 400 years. The grinders are granite cylinders the size of a dinner plate; each one produces about 40 grams of matcha per hour.
Elevation matters because slow growth concentrates flavor. A tea plant at 2,000m takes three times as long to produce a leaf as the same plant at 500m, and the resulting leaf has three times the aromatic compound density. That's why the high-grown teas are expensive: they're not rare exactly, but they take three times as long to make.
